Atoms are the smallest pieces of matter, they make up all of the elements and molecules and proteins
and everything else on Earth. They literally make up everything we see, but in the joke they are
suggesting that the atoms lie so don’t trust them!

OK, this is more of a physics joke. A photon is a packet of light. Not only is it literally travelling light
(the illuminating kind), it’s also travelling light (as in not heavy).

The symbol for sodium on the Periodic Table is “Na”, which when said as a word is pronounced like
“Nah”, another way to say “No”.

In chemistry a solution is the proper name for a mixture where one substance is completely dissolved
in another – like sugar or salt in water. Solutions are also the answers to problems!

“0K” here actually stands for zero Kelvin. Kelvin is a temperature scale in which zero is the coldest
possible temperature, referred to as absolute zero, where molecules cease to move. A person
wouldn’t actually be OK if cooled to absolute zero!

This is a play on the phrase “If you’re not part of the solution, you’re part of the problem”. But in
chemistry, solution is a completely dissolved mixture of two or more compounds, and a precipitate is
a solid that forms from a chemical reaction in a liquid solution. The solid precipitate falls out of
solution, and collects in the bottom of the vial. So a precipitate is DEFINITELY not part of the
solution!
